[0041] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] like Figures 1-10 As shown, the present invention provides a fiber optic clip 1, comprising an internal connection portion 11, which includes an internal connection frame 111 and a locking arm 112. The internal connection frame 111 is surrounded by an internal connection groove 1111, which can be inserted into the housing 100 of the optical module along a first direction. The locking arm 112 extends along the first direction, and a locking protrusion 1121 is provided on a side of the locking arm 112 facing away from the internal connection groove 1111. When the internal connection frame 111 is inserted into the housing 100, the locking protrusion 1121 abuts against the inner wall of the housing 100 along a second direction, which is perpendicular to the first direction.

[0043] In the present invention, the internal frame 111 and the locking arm 112 in the internal connection part 11 of the optical fiber clip 1 cooperate with each other. The internal frame 111 ensures that the optical fiber clip 1 can be stably inserted into the housing 100 of the optical module along a first direction. After the insertion is completed, the locking arm 112 is pressed against the inner wall of the housing 100 along a second direction perpendicular to the first direction through the locking protrusion 1121 thereon, so that when the optical fiber clip 1 is inserted into the housing 100 of the optical module, no shaking will occur, thereby ensuring the reliability and stability of the coupling transmission between the external optical fiber and the internal optical fiber in the optical module.

[0044] Specifically, an inner avoidance groove 1112 is provided at one end of the inner frame 111 facing the notch of the inner groove 1111. The inner avoidance groove 1112 extends through the wall of the inner groove 1111, and the inner groove 1111 is connected to the outside through the inner avoidance groove 1112. The locking arm 112 is provided at the bottom of the inner avoidance groove 1112. This arrangement makes the overall structure of the inner connecting portion 11 more compact and provides the locking arm 112 with a larger elastic deformation space.

[0045] More specifically, two inner avoidance grooves 1112 are provided, located on opposite sides of the inner connecting groove 1111, and a locking arm 112 is disposed in each inner avoidance groove 1112. The two locking arms 112 cooperate with each other to achieve a better locking effect. Furthermore, the two locking arms 112 located on opposite sides of the inner connecting groove 1111 ensure a more balanced force when the inner connecting portion 11 is inserted into the housing 100.

[0046] In this embodiment, the locking protrusion 1121 is long and extends along the third direction. It is located at one end of the locking arm 112 facing the inner avoidance groove 1112. The first direction, the second direction and the third direction are perpendicular to each other, so that the locking is more stable and reliable.

[0047] In another embodiment, an interference rib 1122 is provided on the side of the locking arm 112 facing the inner groove 1111. By providing the interference rib 1122, when the optical fiber plug 2 is inserted into the inner groove 1111, the interference rib 1122 acts on the optical fiber plug 2, making the insertion more reliable.

[0048] The interference rib 1122 may be in the shape of a long strip and extend along the third direction.

[0049] Specifically, the optical fiber clip 1 also includes an external connection part 12 connected to the internal connection part 11. An external connection groove 1211 is provided at one end of the external connection part 12 facing away from the internal connection part 11. The external connection groove 1211 is configured to accommodate a plug of an external optical fiber, so that the external optical fiber can be reliably and stably connected to the internal optical fiber.

[0050] More specifically, the external connection portion 12 includes an external connection frame 121 and a clamping arm 122. The external connection frame 121 surrounds an external connection slot 1211, and the clamping arm 122 extends along a first direction. When the external optical fiber plug is inserted into the external connection slot 1211, the clamping arm 122 abuts against the side wall of the plug to lock it, further ensuring that the external optical fiber is reliably and stably connected to the internal optical fiber.

[0051] More specifically, an external avoidance groove 1212 is provided at one end of the external frame 121 facing the groove opening of the external groove 1211. The external avoidance groove 1212 passes through the groove wall of the external groove 1211. The external groove 1211 is connected to the outside through the external avoidance groove 1212, and the clamping arm 122 is provided at the groove bottom of the external avoidance groove 1212.

[0052] In this embodiment, the internal connection portion 11 and the external connection portion 12 are integrally formed. The external connection portion 12 is provided with two external avoidance grooves 1212, located on opposite sides of the external connection groove 1211. Each external avoidance groove 1212 is provided with a clamping arm 122. The two clamping arms 122 cooperate to more reliably clamp and lock the external optical fiber plug, and ensure more balanced force on the external optical fiber plug.

[0053] Specifically, the outer wall of the external connection portion 12 is provided with a clamping block 1213, which is configured to be clamped in the clamping slot of the housing 100. The above arrangement enables the optical fiber clip 1 to be reliably installed in the housing 100 of the optical module.

[0054] In this embodiment, the clamping block 1213 is disposed on the outer wall of the external frame 121 , is in a long strip shape, and extends along the third direction.

[0055] The utility model further provides a fiber optic adapter, comprising a fiber optic plug 2 and the above-mentioned fiber optic clip 1 , wherein the fiber optic plug 2 is inserted into the internal connection groove 1111 .

[0056] In the optical fiber adapter of the present invention, the internal frame 111 and the locking arm 112 in the internal connection part 11 of the optical fiber clip 1 cooperate with each other. The internal frame 111 ensures that the optical fiber clip 1 can be stably inserted into the housing 100 of the optical module along a first direction. After the insertion is completed, the locking arm 112 is pressed against the inner wall of the housing 100 along a second direction perpendicular to the first direction through the locking protrusion 1121 thereon, so that when the optical fiber clip 1 is inserted into the housing 100 of the optical module, no shaking will occur, thereby ensuring the reliability and stability of the coupling transmission between the external optical fiber and the internal optical fiber in the optical module.

[0057] Specifically, the optical fiber plug 2 includes an inserting portion 21 and a positioning portion 22 connected to each other, wherein the inserting portion 21 is inserted into the internal connection groove 1111 and the positioning portion 22 abuts against the internal connection frame 111. The above arrangement makes the insertion and positioning of the optical fiber plug 2 more accurate.

[0058] More specifically, the end of the optical fiber plug 2 facing away from the optical fiber clip 1 is provided with a first recessed groove 23. A second recessed groove 24 is provided at the bottom of the first recessed groove 23. Multiple insertion grooves 25 are arranged side by side along the walls of the second recessed groove 24. Multiple insertion holes 26 are arranged side by side at the bottom of the second recessed groove 24. The insertion grooves 25 extend along a first direction, with one end extending through the bottom of the first recessed groove 23 and the other end extending through the bottom of the second recessed groove 24. The multiple insertion grooves 25 and the multiple insertion holes 26 are aligned one by one. This arrangement ensures that the internal optical fibers can be more securely assembled with the optical fiber plug 2.

[0059] More specifically, the fiber optic adapter also includes a ferrule 3. The fiber optic plug 2 is provided with a connection hole 27. The ferrule 3 is inserted into the connection hole 27, and one end of the ferrule 3 extends into the external connection slot 1211. The ferrule 3 can be inserted into the external fiber optic plug in an aligned manner, allowing the external fiber to be assembled more accurately with the fiber optic adapter.

[0060] In this embodiment, multiple insertion grooves 25 are arranged side by side along the third direction, multiple insertion holes 26 are arranged side by side along the third direction, two pins 3 are provided, extending along the first direction, and in the third direction, multiple insertion holes 26 are located between the two pins 3.

[0061] Specifically, the optical fiber adapter further includes a fixing member 4, which is disposed on the side of the optical fiber plug 2 facing away from the optical fiber clip 1. The fixing member 4 is provided with a mounting hole 41, and the pin 3 is mounted in the mounting hole 41. The above arrangement can more accurately position and fix the optical fiber plug 2 and the pin 3.

[0062] More specifically, the fixing member 4 has a frame-shaped structure. The wall of the fixing member 4 facing the optical fiber plug 2 is provided with a mounting hole 41 and a passage hole 42 connected to the mounting hole 41. The spacing between the walls of the passage hole 42 gradually increases as it moves away from the mounting hole 41. The ferrule 3 includes a first connecting segment 31, an intermediate segment 32, and a second connecting segment 33 coaxially connected in sequence. The diameter of the intermediate segment 32 is smaller than that of the first connecting segment 31 and the second connecting segment 33. The first connecting segment 31 can pass through the passage hole 42, and the intermediate segment 32 can be moved from the passage hole 42 into the mounting hole 41. When the intermediate segment 32 is in the mounting hole 41, the wall of the fixing member 4 facing the optical fiber plug 2 is sandwiched between the first connecting segment 31 and the second connecting segment 33. This arrangement allows for quick and easy assembly and disassembly of the fixing member 4 from the ferrule 3.

[0063] In this embodiment, the length direction of the channel hole 42 is parallel to the second direction. A clamping hole 41 and a channel hole 42 are configured for each pin 3. When the pin 3 is clamped in the clamping hole 41, the first connecting section 31 is located in the fixing member 4. A threading channel is provided on the fixing member 4 along the first direction. The threading channel is connected to the first sinking groove 23, so that the internal optical fiber can extend into the optical fiber plug 2 through the threading channel.
